When To Take A Pregnancy Test

After implantation, the hormone hCG (human chorionic gonadotropin) will need a bit longer to build up in order for pregnancy tests to detect it. If you are taking a blood test, take it 3-4 days after the date shown. If a urine test is to be taken, do it 4-5 days later.
